Diversity and Distribution of Viruses Infecting Wild and Domesticated Phaseolus spp. in the Mesoamerican Center of Domestication.

ABSTRACT: Viruses are an important disease source for beans. In order to evaluate the impact of virus disease on Phaseolus biodiversity, we determined the identity and distribution of viruses infecting wild and domesticated Phaseolus spp. in the Mesoamerican Center of Domestication (MCD) and the western state of Nayarit, Mexico. We used small RNA sequencing and assembly to identify complete or near-complete sequences of forty-seven genomes belonging to nine viral species of five genera, as well as partial sequences of two putative new endornaviruses and five badnavirus- and pararetrovirus-like sequences. The prevalence of viruses in domesticated beans was significantly higher than in wild beans (97% vs. 19%; p < 0.001), and all samples from domesticated beans were positive for a
